Walkthrough

This mission is pretty straight forward. Head down to the indicated location. You will see bunches of enemies surrounding Heston's squad. Take out this first bunch of enemies (don't forget to pick up their weapons) then go behind Heston's squad and kill the other group of enemies. Once that is done head to the indicated marker, then head towards Heston. You will find him bleeding and tied up, and a Wonsu Assasin holding a minigun saying he will kill Heston. You will automatically take cover bahind a wall. There are grenades in front of this wall, so you can use them against the assasin. Shoot him continuously to bring him down. Huang asks him for Yu Jian, and the assasin tells Huang to "go fuck himself" as he dies.

Script

(At Heston's Safehouse)

Huang: Heston? HESTON?

(The Assassin's Last Stand)

Heston: Huang? Over here!

Huang: Well, you picked a fine time to O.D., dumbass.

Heston: Oh, you're killing me with the humor. Why don't you try one of your lame gags on this guy, and get me the fuck out of here?
